- The unwind record has a flag (alloca_frame) that indicates that
- a function has a variable frame; unfortunately, gcc/binutils
- does not set this flag. Instead, whenever a frame pointer is used
- and saved on the stack, the Save_SP flag is set. We use this to
- decide whether to use the frame pointer for unwinding.
